MobiMatter does not provide eSIM plans for Serbia that include a phone number or SMS capability. Travelers can only purchase data‑only eSIMs from this provider for the destination.
Users who need voice or text communication can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may restrict or block access to specific apps, so it is advisable to confirm the availability of the services you rely on before purchasing.
